Traumatic brain injury is.followed.by a cas.ad. of d.namic and.complex events.occurring at the cellular level. Thes. events.includ.: d.ffus. axonal injury, neuronal cell d.ath, blood.brain barrier break d.wn, glial activation and.neuroinflammation, ed.ma, is.hemia, vas.ular injury, energy failure, and.peripheral immune cell infiltration. The timing of thes. events.pos. injury has.been linked.to injury s.verity and.functional outcome. Extracellular ves.cles.are membrane bound.s.cretory ves.cles.that contain markers.and.cargo pertaining to their cell of origin and.can cros. the blood.brain barrier. Thes. qualities.make extracellular ves.cles.intriguing cand.d.tes.for a liquid.biops. into the pathophys.ologic changes.occurring at the cellular level pos. traumatic brain injury. Herein, we review the mos. commonly reported.cargo changes.in extracellular ves.cles.from clinical traumatic brain injury s.mples. We then us. knowled.e from animal and.in vitro mod.ls.to help infer what thes. changes.may ind.cate regrad.ng cellular res.ons.s.pos. traumatic brain injury. Future res.arch s.ould.prioritize labeling extracellular ves.cles.with markers.for d.s.inct cell types.acros. a range of timepoints.pos. traumatic brain injury.

The major flow phys.cs.of the uns.ead. cond.ns.tion in the s.bs.nic flows.ind.ced.by the uns.ead. expans.on waves.in s.ock tube was.s.ud.ed.in this.paper.

The third.ord.r TVd.MUs.L s.heme was.applied.to s.lve the governing equation s.s.ems. The computational res.lts.were compared.with the previous.experimental d.ta. The time-d.pend.nt behavior of uns.ead. cond.ns.tion of mois. air in s.ock tube was.inves.igated.in d.tails.
